This is gonna make one heck of a fight scene. And where'd Metal Sonic come from? He was missing from this whole comic, why's he here now? But then, same with the Waddle Raichu and Dark Link. ...I guess shouldn't be one to question an Anti-Hero's reasons for being absent.

just throw in dark kirby, dark meta knight, a few nocturnus echidnas... even some upgraded goombas and we'd be set... heck, even some more sonic baddies like tails doll and some others... hell... EVEN SHADOW!
